# LEARN WHAT IT TAKES TO SAVE THE WORLD--Degrees of Freedom: Δ is a climate strategy sandbox currently in early development. Degrees of Freedom: Δ lets you push the climate system beyond typical policy scenarios to see what it would actually take to bend the curve. Test extreme emission cuts, aggressive drawdown, and even “impossible” what‑ifs, and discover which levers matter most for keeping Earth livable. # EARLY ACCESS Degrees of Freedom: Δ will be released in Early Access for 9.99 USD and is planned to increase to 19.99 USD when the full system‑scale climate strategy experience is complete. Buying now supports development of core features like richer Earth system feedbacks and playable nations, and gives you permanent access to all core updates for half of the planned final price. # LEARNING THE PROBLEM FIRST At this stage, Degrees of Freedom: Δ is focused on finishing Forum Mode, where our climate lab and hub teach you what you need to know to win in the later fully playable game. Before you run, you learn to crawl. # CLIMATE CHANGE LITERACY, ENHANCED Want more than the usual “carbon bad” talking points? Degrees of Freedom: Δ focuses on the chain from emissions to radiative forcing to temperature, so you can see how the physics actually adds up. # GROUNDED IN SCIENCE Work with a historically grounded CO₂ and temperature record from 1850–2024, then run multiple scenarios from the present to 2075 to see how greenhouse gases and radiative forcing shape future warming and its impacts. # CREATE MODELS OF YOUR OWN Explore how changes in emissions, growth, and natural sequestration ripple through the climate system, visualize branching futures on interactive graphs, and develop an intuitive feel for time lags and committed warming. # SERVA MUNDUM, EXPLORA FUTURUM! -Save the world, Explore the future!
